[STARRED REVIEW]
Opening with the dramatic story of a fourth grade class’s experience of the 2013 asteroid that landed in Chelyabinsk, Russia, this installment in the celebrated series tells of the study and the effects of asteroids in our solar system. This book describes the work done by several individual scientists who research asteroids, sharing how they collect data and use it to form coherent ideas about these astonishing rocks from space. Through the eyes of the scientists, readers learn about prehistoric collisions that shaped our planet, current methods used for observing asteroids, and what might be done to deal with the potential of a major impact in the future. The text makes complicated concepts understandable for younger readers without oversimplifying, and the accompanying photos and graphics are both informative and appealing. The scientists’ enthusiasm for their work is palpable, which makes for compelling reading, and their experiences allow readers to visualize themselves in similar roles as they think about their futures. VERDICT Another excellent entry into the series. Purchase this to excite space buffs and inspire future scientists.—Sarah Reid, Four County Library System, NY
These entries follow researchers as they document the unfolding ecological dynamics of a pristine volcanic island (Surtsey) and trace the paths of asteroids that could potentially reach Earth (Impact). Surtsey features Erling ólafsson, an entomologist with a lifelong interest in the volcanic island that formed off the coast of Iceland in 1964. He was part of the first science team on the island when he was just a college student and, over a decades-long career, has continually returned to Surtsey to observe the growth and diversification of life there. Impact profiles a collection of astronomers, geologists, and meteorite hunters to examine the history of strikes to Earth and gauge the risks of future encounters. The discussion ends with a fascinating look at the technologies proposed (or in development) to protect Earth from a major impact. Both volumes prominently feature the research methods and tools of science. Burns, who traveled with Icelandic researchers to Surtsey, meticulously documents every detail of life in a remote field station, from the particulars of trapping insects to the extremes taken to minimize human impact on the island. Vivid photographs of field locations in both volumes convey, respectively, the rocky landscapes of Surtsey and its inhabitants and the impressive size of the Arizona impact crater. Impact also contains excellent diagrams, maps, and artistic renderings. Extensive appended resources point readers to additional information. danielle j. ford
